如何使用“留言”功能使用消息 ID 检查不同 CAN 上特定消息可用性的事件

Question

我正在 CANoe 中离线运行超过 15 个 CANS 的测量日志数据文件。我想在运行离线日志文件时检查来自不同 CAN 总线的特定 CAN 消息可用性。 我尝试使用“on Message *”事件，只执行一次，因为我想将该结果保存到文本文件中。 问题是每次执行其他条件时。 对于给定的问题有任何简单的解决方案吗？

谢谢

Variable
     dword CANFD_01= 0x1A55549B 
       int MessageExecuted = 0;
     dword readHandle = 0;
     dword readHandle_01 = 0;
      
    
    on start
    {
      setFilePath(path, 1);
      readHandle = openFileWrite("Result.txt",0);
      readHandle_01 = openFileWrite("Result_02.txt",0);
    }
    
    on message *
    {
      
      if(MessageExecuted == 1) return;
      {
      if(this.id == CANFD_01)
          {  
            i = snprintf(buffer, elcount(buffer),"CANFD_01 is there  \n");
            filePutString(buffer, elcount(buffer), readHandle);         
          }
       else 
          {
          i = snprintf(buffer, elcount(buffer),"CANFD_01s not there with ID: %d\n",this.id);
              filePutString(buffer, elcount(buffer), readHandle_01);
          }
          MessageExecuted = 1; 
      } 
}

您想要确认 15 个不同 CAN 网络中的特定帧 ID。以下内容对您有用吗？

variables
{
  dword frame_of_interest = 0x1A55549B; /* CANFD_01 */
  dword channel_hits[16];
}
  
on message *
{
  if( 16 > this.can )
  {
    channel_hits[this.can]++;
  }
  else
  {
    write("Channel ID out of range: %d", this.can);
  }
}

on stopMeasurement
{
  byte i;
  
  for(i=0; i<16; i++)
  {
    if( 0 < channel_hits[i] )
    {
      write("Channel ID: %d (hits=%d)", i, channel_hits[i]);
    }
  }
}
